That might be a tricky thing to do but heres a few ways if you can't get a new one. First the challenging part might be getting it back. First take some hot water and pour dish soap into a bowl along with the water. Soak your retainer for a few minutes. Then rinse it in cold water. After that to get ALL the germs out. Then take an old toothbrush and SCRUB it clean. Put more soap on the tooth brush. Then let your retainer air dry. Then it should be back to normal :) If you have small crack sin your retainer take a toothpick, a paperclip, or safety pin and push the dirt ou tout it with one of theese pointy tools.
